Who it's for
Cooling a home that needs about 4 tons of capacity, replacing an aging AC condenser.
The standout number
SEER2 17.25 (EER2 12.4 at peak 95°F) — higher means lower cooling bills.
The catch
A central AC is contractor-installed — the number that matters is the installed price with a matched coil, so get a few local quotes.

Rebates & incentives
Central AC rebates are thinner than heat-pump rebates and usually require a high SEER2 tier. The federal 25C credit expired December 31, 2025; the live money is state and utility programs. Check what applies where you live on our rebates page.

Frequently asked questions
How efficient is the ARMSTRONG AIR A7AC22V48P-**B?
It is rated SEER2 17.25 and EER2 12.4. SEER2 is the seasonal cooling efficiency — the higher the number, the less electricity it uses to remove the same heat. Current federal minimums are SEER2 13.4–14.3 depending on region, so this unit sits well above the floor.
What does the ARMSTRONG AIR A7AC22V48P-**B cost to run?
We estimate about $497 a year to cool with it at U.S. average electricity prices and a typical cooling season. Your climate and local power price move the number — cooling cost scales inversely with SEER2.
What refrigerant does the ARMSTRONG AIR A7AC22V48P-**B use?
R-454B, which has a global-warming potential (GWP) of about 466. This is one of the lower-GWP refrigerants replacing R-410A.
Is the ARMSTRONG AIR A7AC22V48P-**B the same as other brands?
Yes. The same certified condenser is sold under 2 brand names — ARMSTRONG AIR, Airease — because these labels share a parent manufacturer. The specs are identical; the badge on the cabinet is the main difference. Compare installed prices across whichever brand a local contractor carries.
Where can I buy the ARMSTRONG AIR A7AC22V48P-**B?
Central AC condensers like this are installed by a licensed HVAC contractor, who matches the coil, pulls the permit and charges the refrigerant. Get a few installed quotes and compare the total price, not just the equipment.
Sources. Performance ratings from the AHRI Directory (cited by reference number 218669734; not a verbatim mirror) and ENERGY STAR certification data. Annual cooling cost and percentile figures are computed by Verified HVAC Data from published ratings and EIA U.S. average electricity prices — see our methodology. Refrigerant GWP is the IPCC value for that refrigerant. We publish no star ratings and take no payment for placement. "Not published" means the source registry doesn't disclose it — we never fill a spec with a guess.
